TYPE-WRITER WORD-COUNTER.

SPECIFICATION forming part of Letters Patent No. 717,151, dated December30, 1902.

Application filed April 16,1902. fierial No. 108,190. (No model.)

To all whom it may concern: I

Be it known that I, ROBERT ALLEN, a citizen of the United States,residing at Bigtimher, in the county of Sweet Grass and State ofMontana, have invented certain new and useful Improvements inWord-Counting Attachments for lype J/Vriting Machines; and I do declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilledin the art to which itappertains to make and use the same.

This invention relates generally to typewriting machines, andparticularly to wordcount-ing attachments for type-writing machines ofthat class in which the type-levers and the space-operating mechanism isoperated by rock-shafts to which motion is imparted by the depression ofthe keys and space-bar, such as the machine commonly known as the SmithPremier, and my invention has for its object to provide a simple,durable, and comparatively inexpensive device adapted for attachment toany typewriting machine of the class above mentioned for counting orregistering each word written by the machine and without liability ofaccidentally registering more than one word at a time; and it consistsin the parts and combinations of parts hereinafter described andclaimed.

In the accompanying drawings, forming a part of this specification,Figure l is a detail perspective view of a portion of the back or rearframe and one of the side frames of a type-writing machine of the typenamed, showing my counting attachment in place thereon; Fig. 2, a bottomplan view of a portion of a type-writing-machine frame, showing mydevice in position; Fig. 8, a side elevation of my device in position;Fig. 4, arear elevation of the same; Fig. 5, a detail plan view of theoperating-levers; Fig. 6, an edge view of the letter-key-operatedlevers; Fig. 7, a plan view of said levers, and Fig. 8 an edge view ofone of the supporting-bars.

Similar letters refer to similar parts throu ghout all the views.

Referring to the drawings, A represents a portion of one of the sideframes of a typewriting machine, and B a portion of the rear frame. Tothe rear frame or a plate attached to said frame is connected the grateC, as is usual in the class of machines above de scribed, by books orbrackets, so as to be capable of longitudinal motion when operated uponby the fingers projecting from the rockshafts, (not shown,) which areoperated by the letter-keys in order to move the carriage and form thespaces between the letters,while a rock-shaft D, having its bearings inthe front and rear walls of the machine, is operated by means of acurved arm E, carried by the space-bar, (not shown,) coming in contactwith the finger or crank F on said shaft to rock the latter at eachdepression of the space-bar, and thereby operates the grate through thepin and finger F to shift the carriage to form a space between thewords.

The above-described mechanism is common in the class of machinesmentioned above and of which a full description may be found in UnitedStates patent to Alex. T. Brown, No. 465,451, dated December 22, 1891.

In applying myinvention to the machine I first arrange thesupporting-bars G across the bottom of the machine from side to side,catching the stationary or rigid hooksotthereof onto one of the sideframes and the adjustable hook I) at the opposite ends of the bars ontothe other side frame and by tightening the nuts a secure the same firmlyin position. To one of the bars G is pivotally secured the end of a longlever H, which extends to and enters one of the openings in the grate Cor, as shown, in a recess cl, formed in said grate therefor. To thelever H is pivotally attached a short link or leverl, the other end ofwhich is similarly attached to a lever J, one end of which is pivotallysecured tothe other bar G. The lever H extends across the bars G,

and the link or lever I extends at right angles from the said lever H,while the lever J extends from one bar G to the other, and its free endrests on the latter. Thus it will be observed that the movement of thegrate C is imparted to lever II and that the latter through link orlever I moves the free end of lever J and causes it to slide on the barG, on which it rests.

To the rock-shaft D is connected one end of a slide-rod K by means of aclamp L, in which the end of the rod is loosely hung, the other end ofsaid rod being pivotally attached to the end of a lever M, which ispivotally supported near its lower end from the bracket N, so that thelongitudinal movement of the rod K imparted by the rock-shaft D causesthe lever M to swing on its pivot. A lever O is pivotally secured at itsupper end to the bracket N in position to be engaged by the lever M whenit is swung toward the former, and thus rock or swing the lower end ofthe lever 0 toward the frame. The lever O is pivotally attached at itslower end to a link P, as is also the end of a lever Q, which isconnected at its upper end to the slide-rod R of the registering deviceS. The lever Q passes through a perforated lug or eyebolt T, secured tothe bracket N, whereby it may be tilted or rocked by link P when thesame is moved in order to push said rod R in. To the end of link P isalso pivotally attached a trigger or trip-lever U, having a curved edgeagainst which a pin V, projecting from rod K, strikes as the rod ismoved outwardly by rock-shaft D in order to tilt or raise one end ofsaid lever U up and in position to allow the end of lever J to passthereunder when it is operated by the movement of the grate C inresponse to the operation of the space-bar. When the space-bar isreleased and the grate is moved back into its normal position by thespring (not shown) commonly employed for the purpose, the trigger ortrip-lever U drops back to its normal position in the path of lever J tobe engaged thereby when the same is operated by the lever-key which isfirst depressed after the depression of the space-bar, and thus tiltlever Q, which withdraws the rod R and causes the operation of theregister mechanism to register a Word. The end of the trigger ortrip-lever U is prevented dropping below the path of lever J by its rearend engaging the end of lever Q.

WV is a bracket secured to'the side frame of the machine by hooking oneend thereover and the other passing under the frame and being secured bya set-screw or otherwise.

I make no claim for the registering device,

as any suitable type of such devices may be used.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a word-counting device for type-writ,- ing machines, thecombination, with the space-bar rock-shaft, the grate, and a registeringdevice, of a rod having one end connected to the said rock-shaft, apivoted lever having one end connected pivotally with said rod, meansoperated by said rod and lever for moving the slide-rod of the registerin one direction, and means operated by the grate for moving said rod inthe opposite direction.

2. In a word-counting device for type-writing machines, the combination,of a registering device having an operating slide-rod, a

pivoted lever connected at one end to said rod,

a link connected to the other end of said lever, a pendent leverconnected to said link, a lever-arm for tilting the pendent lever, arock-shaft, a rod connecting said rock-shaft and lever-arm, a trigger ortrip-lever tripped by said rod, and means for engaging said triggerortrip-lever to movethe slide-rod to its normal position.

3. In a word-counting device for typewriting machines, the combination,of a rockshaft, a grate, a pivoted lever having its free end engaged bysaid grate, a parallel lever, a link connecting said levers, a triggeror triplever arranged to be engaged by the free end of said parallellever, a registering device having a slide-rod, a lever connected tosaid trip-lever and to said slide-rod, whereby the slide-rod is moved inone direction, and means operated by the rock-shaft for moving theslide-rod in the opposite direction.

In testimony whereof I affix my signature in presence of two witnesses.

ROBERT ALLEN.
